Cloudflare Email Routing

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly coherent for managing Cloudflare Email Routing through OOMOL, but its first-time setup includes unverified remote installer commands that could run arbitrary local code.

Before installing, review the OOMOL CLI installer through a safer documented method and confirm you trust OOMOL with Cloudflare Email Routing operations. Use extra care with update and delete actions because they can overwrite or remove routing rules.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

External Script Fetching

Confidence

Finding

The skill instructs users to install software via a remote script piped directly into a shell, which executes unreviewed code fetched at runtime. If the remote host, transport, installer, or distribution path is compromised, this can lead to arbitrary code execution on the local machine with the user's privileges.

Finding

The skill description says to use this skill for ANY Cloudflare Email Routing request and instead of calling the API directly, which is an overly broad trigger that can cause the agent to invoke the skill in situations where a narrower or safer path would be more appropriate. Broad auto-selection language increases the chance of unnecessary tool use, including write or destructive actions in a sensitive administrative domain.
